It is highly recommended that you do not open or close

the stop valves when the outdoor temperature is below

-5°F (-21°C) as this may cause refrigerant leakage.

Make sure power is turned on for at least 12 hours

after periods of being powered down in an 32 °F (0° C)

environment or lower.

Do not touch the fins of the coil. Touching the coil fins

could result in damage to the fins or personal injury such

as skin rupture.

Ensure the power circuit capacity is adequate for all loads

connected to the electrical service panel. Increase the

conductor and panel capacity if the total electrical loads

exceed the power source capacity.

Contact the power utility if the power provided is below

equipment rating plate requirements.

Be sure to install a breaker of the specified capacity.

Regulation of cables and breaker differs from each

locality, refer in accordance with local rules.

Do not use existing refrigerant lines.

Use refrigerant tubing that is clean and free of any

contamination which may cause damage to the system

including sulfur, copper oxide, dust, metal chips, powder,

oil or water.

Avoid brazing lines together. Use a continuous length of

copper tubing as oxides formed during improper brazing

techniques can damage the equipment.

Do not use copper pipes that have a collapsed, deformed,

or discolored portion (especially on the interior surface).

Otherwise, the expansion valve or capillary tube may

become blocked with contaminants.

Improper line sizing will degrade performance. Peak

pressure of R410A is much higher than R22. Use copper

tubing with adequate wall thickness.

To prevent breaking of the pipe, avoid sharp bends. Bend

the pipe with a radius of curvature of 4 in. (100 mm ) or

more.

If the pipe is bent repeatedly at the same place, it will

INSTALLATION INSTRUCTIONS

10 31-5000001 Rev. 7

ENGLISH

Step 2 - Installation of the Indoor Unit

A. Select the Indoor location:

• Do not expose the unit to unusual heat sources or

steam outlets.

• Select a location where there are no obstacles in

front of the unit.

• Make sure that condensate drainage can be

conveniently routed away.

• Do not install near a doorway.

• Ensure that the space around the left and right of

the unit is more than 4”. The unit should be installed

as high on the wall as possible but allow a minimum

of 4” from the ceiling.

• Use a stud finder to locate and mark stud locations

for mounting and to prevent unnecessary damage

to the wall.

• Install in a location that is strong enough to

withstand the full weight and vibration of the unit.

• Leave enough space to allow access for routine

maintenance.

• Select a location that gives easy access to removing

and cleaning air filters.

• Install in a location that is 3 ft. or more away from

other electrical appliances, such as televisions and

audio devices.

B. Install the Mounting Plate

• Remove plastic bag, tape, and mounting plate from

the back of the indoor unit.

• Place the mounting plate on the wall in the desired

location taking into account the minimum clearances

necessary for proper operation.

• Using a level, verify that the mounting plate is

horizontal and mark the screw locations.

• Attach the mounting plate to the wall with the

supplied screws.

• If not able to align all screw holes with studs, wall

anchors are supplied.

• Be sure that the mounting plate has been attached

firmly and that applied weight is evenly distributed

by each screw. (At least one screw in wall stud,

others can use wall anchors.)

• The piping for the indoor unit may be routed to and

from the unit in one of several directions: left, left

rear, right, right rear, or right below. See Illustration

on page 7.

Step 1 - Preparation Cont.

NOTES:

• OD unit cannot hang from a ceiling or be stacked.

• If installing the OD unit with a fence or rail guard around it,

ensure that accumulated snow, debris, etc… will not block

the air inlet or the coil exchanger.

• Ensure ventilation in case of refrigerant leakage. R-410A is

a safe, nontoxic, and nonflammable refrigerant.

• Avoid installing the OD unit where corrosive gases, such as

sulfur oxides, ammonia, and sulfurous gas are produced. If

unavoidable, consult with an installation specialist about

using a corrosion-proof or anti-rust additive to protect the

unit coils.

• Do not install the outdoor unit near the edge of a balcony.

Otherwise, children may climb onto the outdoor unit and fall

off of the balcony.

• Do not install the outdoor unit in the following areas: Areas

heavily laden with oil or greasy vapors such as kitchens. Oils

and grease will create sticky layer on the coil and also cause

drainage problems, thus degrade unit performance.

• Corrosive areas that can potentially have combustible

gas leaks, contain suspended fibers or flammable dust, or

flammables such as paint thinner or gasoline can cause fires.

• Areas that contain small animals, rodents, reptiles or insects

that can infiltrate the equipment and cause damage to

internal components.

• Area where animals may urinate on the unit or ammonia

may be generated.

• If the outdoor unit must be installed in an area within easy

reach of the general public,Install as necessary a protective

fence or the like to prevent their access.

• If the outdoor unit is installed in a cold region that is

affected by snow accumulation, snow fall, or freezing, take

appropriate measures to protect it from those elements. To

ensure a stable operating, install inlet and outlet ducts.

• Make sure the outdoor unit is installed level and is stable.

Install snow protection hood as necessary.

• Avoid salty places such as the seaside for installation where

air conditioner trouble is liable to occur.

• Install the outdoor unit in a location that is away from

exhaust or the vent ports that discharge vapor, soot, dust,

or debris.

• Install the unit where it will not be tilted by more than 3°.

However, do not install the unit with it tilted towards the

side containing the compressor.

• When installing the outdoor unit where it may exposed to

strong wind, fasten it securely.

• It is recommended that unit be installed under a canopy or

elevated on a high stand.

• Protect the drain line from freezing in areas where

temperature drops to 32°F (0°C) or lower.

• Please set up the outdoor unit in a high place and please

do not arrange the frame of installed stand under the

drain port, because the water dropped from the drain port

repeats freezing and accumulating, and may block the drain

port.

• Do not use mineral oils on flared parts. Prevent mineral

oil from entering the refrigerant system. Introduction of

mineral oil may reduce the system life.

• Be sure to use an inert gas such as nitrogen while brazing

any refrigerant lines to prevent any oxidation

• Be sure not to exceed refrigerant tubing length limits

mentioned in table on page 15 for different models to

ensure smooth operation of the unit. Otherwise the

equipment life cannot be guaranteed.

D. Electrical Connections for the Indoor Unit

NOTE: Be certain all wiring complies with local building

codes and NEC and that the supply voltage for this

system is correct.

• Place the indoor unit on a solid work surface before

making electrical connections.

• To make the electrical connections for the indoor

unit, both the outer plastic and inner galvanized

steel cover plate must be removed.

• Raise the front cover to access the screws for

removing these covers.

• Rout the 14/4 AWG wiring through the slot in the

back of the unit and into the front access panel.

• Using a wire stripper, remove the insulation and

separate the 4 wires.

• Make wiring connections at each terminal according

to wiring diagram. (Take note of the color of the

wire at each terminal and ensure the wires are

connected to the outdoor unit accordingly.)

• Ensure each wire is under the screw terminal plate

and the plate is tightened.

• Ensure the 14/4 cable is secured under the strain

relief bracket.

• After the terminal block wiring is completed, replace

both cover plates and lower the front casing.

E. Mount Indoor Unit to Mounting Plate

• Bundle the refrigerant piping, drain piping, and wiring

with tape and carefully rout the bundle through the

piping hole.

• With the top of the indoor unit closer to the wall,

hang the indoor unit on the upper hooks of the

mounting plate. Slide the unit slightly side to side to

verify proper placement.

• Rotate the lower portion of the indoor unit to the

mounting plate, pushing the unit up slightly, rotate

the lower part of the unit fully against the wall, then

pull down do the lower hooks engage the brackets.

(see illustration)

• Verify the unit is secured and flush to the wall.

• Indoor Unit installation is finished at this time.

F. Condensate Drainage Pipe

• Verify the condensate drain line has a constant pitch

downward for proper water flow. There should be

no kinks or rises in the tubing which may cause a

trapping effect of the water (see illustration).

Optional: Can use PVC pipe by connecting a 1” ID

PVC pipe to the drain line coming out of the wall and

running to desired location.

• Slightly raise the entire unit.

• Pull the lower portion of the unit off the lower hooks

and pull slightly away from the wall.

• Lift the upper portion of the unit off the upper hooks.

C. Install the Tubing

• Always use new clean copper tubing. Never reuse

tubing if replacing an existing system.

• Measure and mark the location where the piping hole

is to be drilled.

• If pipe location will be on the left side of the unit,

follow these steps to move the drain pipe.

1. Remove the stopper in the left drain hole and

knockout the molded plug inside the port.

2. Transfer the corrugate drain hose from the right side

to the left side.

3. Insert stopper into right side drain port. Using soap

as a lubricant and a small screwdriver will allow for

easier seating of the stopper.

• Drill the lineset hole using a 2 1/4” hole saw. Angle

the drill with a downward pitch to the outside wall so

that the outside wall hole will be at least a ¼” lower

than the inside hole. This allows for proper drainage

of condensate.

• Install the lineset hole flange at the hole opening on

the inside wall.

NOTE: The flange is prescored. It may be necessary

to modify the flange to fit properly behind the wall unit

housing.

D. Wiring Error Check

• This unit is capable of automatically checking for wiring errors

between the indoor and outdoor units.

• To enter the wiring error check test, remove power to unit,

place all 4 DIP switches on the test board in the “ON” position

(illustration 6). Reapply power to the unit. The system will now

enter “Wiring Error Check”

• The numeric display will initialize and begin to alternate

between the compressor working frequency (a number

representing the Hz value) and “CH” (Checking).

• As the check is being performed, all units that are properly

connected will be indicated by the corresponding LED for that

circuit being lit constantly. (LED 1 = piping circuit A, LED 2 =

piping circuit B, ...)

• After the check has completed, if all wiring is correct,

the numeric display will indicate “0” and the single LEDs

representing the individual circuits for the connected indoor

units will be lit constantly.

• If there are any miswired units, the numeric display will flash

“EC” (error connection), and th corresponding LED for the

miswired circuit will flash. Check and correct the wiring as

needed.

• Refer to the chart shown below. (Table 2)

• When the test is complete, remove power to the system and

return the 4 DIP switches to the OFF position. Reapply power

to the the system. The test is complete.

• If the self-check is not possible, check the indoor unit wiring

and piping in the usual manner.

Step 3 - Installation of the Outdoor Unit (Cont.)

G. System Evacuation

NOTE– Do not open service valve.

• Remove the suction line cap and attach a manifold

gauge, micron gauge, and vacuum pump to

the suction line port using adapter AD-87 (see

illustration).

• Evacuate the system to at least 350 microns.

• Close the vacuum pump valve and check the micron

gauge. If the gauge rises above 150 microns in 60

seconds, the evacuation is incomplete or there

is a leak in the system. If the gauge does not rise

above 150 microns in 60 seconds, the evacuation is

complete.

• Once evacuation is complete, remove the adapter

and hose connection from the suction line port and

replaced the cap.

F. Leak Test

2U18MS* and 3U24MS* do not have main service

valves. Perform the following steps for EACH line set.

4U36MS*, 2U20EH*, 3U24EH*, and 4U36EH* have a

main service valve. Performing the following steps will

test ALL line sets.

• Remove the cap on the service valve.

• Using a tank of dry nitrogen and approved regulator,

charge the system with 150 psig of dry nitrogen

using mini-split adapter to connect the valve.

• Check for leaks at the flare fittings using soap

bubbles or another detection device. If a leak is

detected, make repairs to the fittings and recheck.

If no leaks are detected within 3 minutes, proceed.

• Using the same tank/regulator, charge the system

to 300 psig.

• Check for leaks as earlier. If no leaks are detected

within 3 minutes, proceed.

• Using the same tank/regulator, charge the system

to 500 psig.

• Check for leaks as earlier. Keep system pressurized

for at least 20 minutes.

WARNING Do not use acetylene, oxygen or

compressed air or mixtures

containing air, oxygen, or combustible gases for

pressure testing. Do not use mixtures of hydrogen

containing refrigerant and air above atmospheric

pressure for pressure testing as they may become

flammable and could result in an explosion. Refrigerant,

when used as a trace gas, should only be mixed with dry

nitrogen for pressurizing units. Failure to follow these

recommendations could result in death or serious

injury as well as equipment or property damage.

E. Install Copper Lineset

• For 2U20EH2VH*, 2U18MS2VH*,

3U24EH2VH*, 3U24MS2VH*, 4U36MS2VH*,

and 4U36EH2VH* see table on page 15.

• Cut the line set to length.

• Place nut over the pipe and then flare with the

R-410A flaring tool.

NOTE: Follow standard practices for creating

pipe flares. When cutting and reaming the

tubing, use caution to prevent dirt or debris

from entering the tubing. Remember to place

nut over the tubing before flaring.

• To join the line set, directly align the tubing

flare to the fitting on the other pipe. Slide the

nut onto the fitting and hand tighten.

• Torque the fittings according to the

specifications shown in the torque chart below.

Forced fastening without careful centering may

damage the threads and cause a refrigerant leak.
